[0097] Figure 6 It is a diagram illustrating a configuration of a main part of a source driver in a liquid crystal display device according to a second embodiment of the present invention. In the figure, the main difference between this embodiment and the above-mentioned first embodiment is that a selector is provided between the sampling memory and the redundancy amplifier, and the selector connects only the source wiring connected to the redundancy wiring. The output corresponding data signal is selectively output to the redundant amplifier side. In addition, the same code|symbol is attached|subjected to the element common to the said 1st Embodiment, and the overlapping description is abbreviate|omitted.

[0098] That is, if Figure 6 As shown, in the present embodiment, the source driver (data wiring drive unit) 23 is provided with a sampling memory 41 as a storage unit; and a first latch 42 and an amplifier output unit 43 sequentially connected to the sampling memory 41...

Abstract

A liquid crystal display apparatus (display apparatus) (1) provided with a liquid crystal panel (display unit) (2) for displaying information includes a source driver (data wiring drive unit) (23) having an amplifier output unit (33) for outputting to each of a plurality of source wirings (Sm to S(m+m)) a source signal (data signal) according to information to be displayed on the liquid crystal panel (2), a redundant wiring (Y) provided as a backup wiring for the source wirings (S), and a redundant amplifier (36) capable of outputting to the redundant wiring (Y) a source signal according to information to be displayed on the liquid crystal panel (2), the redundant amplifier (36) outputting to the redundant wiring (Y) and a source wiring (Sm) to which to the redundant wiring (Y) is connected a corresponding source signal at a timing earlier than the amplifier output unit (33) by a prescribed amount of time.

Description

technical field [0001] The present invention relates to a display device having a display unit for displaying information such as characters and images, and more particularly to a display device having a plurality of data wirings and redundant wirings for inputting data signals corresponding to the information. Background technique [0002] In recent years, for example, liquid crystal display devices have been widely used in liquid crystal televisions, monitors, mobile phones, and the like as flat panel displays that are lighter in weight than conventional picture tubes. Such a liquid crystal display device includes a liquid crystal panel as a display unit for displaying information such as characters and images, and the liquid crystal panel is provided with a plurality of data lines (source lines) and a plurality of scan lines (source lines) arranged in a matrix. gate wiring); and a plurality of pixels having switching elements such as thin film transistors (TFT: Thin Film ...
